Role of biotic interactions on seasonal migrations of the macrozoobenthos living in the upper tidal-flat of the Mont-Saint-Michel bay, France
Provedor de dados: 5
Autores: Meziane, T; Retiere, C.
On the tidal flat of the western part of the Mont-Saint-Michel bay, the macrozoobenthos of the upper flat is characterised by an assemblage of the Macoma balthica community. The dominant species are M. balthica, Nereis diversicolor and Corophium volutator. A field monitoring during a 1-year period along a four-stations transect perpendicularly to the shore showed that biotic interactions affected the local distributions of these species. This was particularly obvious from late spring to late summer while, because of the density increases, competitions for space and/or resources were induced, which stimulated migrations. Intra-specific competition seemed to induce the migration of the 1-year-old M. balthica. Consequently, the migration of the young bivalves...

Exploitation of intertidal feeding resources by the Red Knot Calidris canutus under megatidal conditions (Bay of Saint-Brieuc, France)

The feeding ecology of the red knot has been widely studied across its wintering range. Red knots mainly select bivalves and gastropods, with differences between sites due to variation in prey availability. Shorebird’s diet is also influenced or controlled by the tidal regime. The aim of this paper is to demonstrate the adaptation of foraging red knots to the megatidal environment. The variation in their diet during tidal cycles was studied in the bay of Saint-Brieuc, a functional unit for this species. The method used combined macrofauna, distribution of foraging birds and diet data. Comparative spatial analyses of macrofauna and distribution of foraging red knots have shown that the bay's four benthic assemblages are exploited by birds. By analysing...
